Overview
Klaviyo is built for event-driven marketing across email and SMS, with strong ecommerce patterns. HelloGrowthCRM can push lifecycle events—lead created, meeting booked, deal won—so Klaviyo flows react to real revenue milestones, not only storefront activity. Profile mapping should include identifiers Klaviyo can merge on (email, phone). This integration shines when sales milestones should trigger nurture or handoff campaigns.
What data is involved
- Profile properties: identity, company, region, product interest.
- Custom events: e.g. LeadCreated, DealStageChanged, DealWon with timestamps.
- Optional: revenue or ACV fields for VIP segmentation (handle PII policies).

FAQ
Governance
Treat API keys and webhooks as production secrets. Align field mapping with your privacy policy and regional regulations (GDPR, marketing consent, telemarketing rules). Your admin controls which roles can install or edit integrations.
